Hi,
WorkstationPlayer only runs on Windows or Linux as host.
For macOS you must use VMware Fusion in order to run your Windows VM with SQL.
Having said that. I don't know how powerful your macbook air is (CPU, RAM and free disk space), but for running any serious SQL engine it might be a tad light.
If your database is not too big then you are probably fine. If your database is > 10 GB then I doubt strongly that you will have a great experience.
